The Stroke Path command strokes a path in
the image. There are two ways you can stroke the path, either by using
a paint tool, or without using one. There are various options which you
can use to specify how this stroke should look.

Nota

This command is active only if there is a path in your image.

3.18.1. Activating the Command

You can access this command from the image menubar through
Edit → Stroke Path.

You can also access it by clicking on the button with the same name
in the Path dialog.

3.18.2. Description of the Dialog Window

Figura 16.20. The “Choose Stroke Style” dialog window

The Choose Stroke Style dialog box allows you to
choose between stroking the path with the options you specify or
stroking it with a paint tool. If you stroke the path with a paint
tool, the current paint tool options are used to draw the stroke.

Stroke line

The stroke is drawn with the current foreground color,
set in the Toolbox. By clicking on the triangle next to
Line Style however, the dialog expands
and you can set several additional options:

Line Width

You can set the width of the stroke using the text box.
The default unit is pixels, but you can choose another
unit with the drop-down list button.

Solid color / Pattern

You can choose whether the line is drawn in the
Solid or the
Pattern
style. Here, Solid and Pattern are distinct from the dash
pattern. If you select a Solid line with no dash pattern, an
unbroken line is drawn in the foreground color set in the
Toolbox. If you select a Patterned line with no dash
pattern, an unbroken line is drawn with the pattern set in
the Toolbox. If you select a line with a dash pattern, the
color or pattern is still determined by the foreground color
or pattern set in the Toolbox. That is, if you select a
marbled pattern and Patterned, dashed lines, the dashes are
drawn in the marbled pattern

Line Style

This drop-list brings some detailed options :

Cap Style : You can choose the shape of
the ends of an unclosed path, which can be
Butt, Round
or Square.

Join Style :
You can choose the shape of the path corners by
clicking on Miter,
Round or Bevel.

Miter limit :
When two segments of a path come together, the mitering of
the corner is determined by the Miter Limit. If the strokes
were wide, and no mitering were done, there would be pointed
ends sticking out at the corner. The Miter Limit setting
determines how the gap, formed when the outer edges of the
two lines are extended, will be filled. You can set it to a
value between 0.0 and 100.0, by using the slider or the
associated text box and its arrows.

Left: Limit=0; Right: Limit=5;

Dash Pattern :
On the pixel level, a dashed line is drawn as a series of
tiny boxes. You can modify the pattern of these boxes. The
black area with thin vertical lines represents the pixels of
the dash. If you click on a black pixel, you remove it from
the dash. If you click on a white pixel, you add it to the
dash. The gray areas indicate how the pattern will be
repeated when a dashed line is drawn.

Dash Preset :
Instead of making your own dash pattern, you can choose
one from the drop-down box. This pattern will
then be displayed in the Dash pattern
area, so you can get an idea of how it will look.

Anti-aliasing :
Curved strokes or strokes drawn at an angle may look jagged
or stair-stepped. The anti-aliasing option smooths them
out.

Stroking with a Paint Tool

Paint Tool

You can select a paint tool to use to draw the stroke from
the drop-down box. If you do that, the currently-selected
options of the paint tool are used, rather than the settings
in the dialog.
